Fisher Fattrax, Tioga Farmer John, Specialized Hardpack, etc., were all good tires from 87 ish. They're difficult to find in rideable condition. Your best bet would have been the TimbukII repops from FirstFlight, but even those are getting tough to come by. Modern skinwall options are pretty scarce in 26"... Onza Canis and the FirstFlight Ritchey Zmax are viable options if you can get your hands on them
